Ponds Searched: ⢠Salamanders found; â Salamanders not found; * Studied population confluence of the Peace and Beaton rivers in British Columbia. The newly discovered Peace River populations are at an elevation of approximately 500 m and are found within the relictual aspen parkland typical of the upper Peace Valley (Russell and Bauer 1993), 200 km from the mountains, unlike the previously reported Ambystoma macrodactylum habitat in Alberta (Russell and Bauer 1993). The area near Fairview averages 45 cm annual precipitation and 119 frost free days. A voucher specimen from this locality has been placed in the University of Alberta Vertebrate Zoology museum (UAVZ 3000). All the ponds in which these salamanders have been found are adjacent to steep-sided ravines (up to 200 m deep) draining to the Peace River, and all are within 4 km of the Peace River itself. Most ponds are due to anthropogenic ("man"-made) dams creat- ed for water storage on spring runoff channels. The water ranges from relatively clear to extremely muddy due to cattle use. Surrounding plant commu- nities mostly are Aspen Poplar (Populus tremuloides) forest, with the exception of two ponds surrounded by pasture land. Other amphibians pre- sent in the same ponds are the Wood Frog {Rana syl- vatica) and the Striped Chorus Frog {Pseudacris tris- eriata maculata). The Red-Sided Garter Snake {Thamnophis sirtalis parietalis) and the Wandering Garter Snake (Thamnophis elegans vagrans) have also been observed in the vicinity of some of the salamander ponds. The Western Toad {Bufo boreas boreas) has been observed near the Peace River in this general area. The salamanders have an uninterrupted yellow- green dorsal stripe that exhibits irregular borders with deep undulations. This stripe begins at the snout and continues to the tip of the tail, and contains a variable number of irregular spots of ground color (bl
